Kylie Jenner shocked followers with her new Instagram video. According to a report from Us Weekly, the underage reality star grabbed her boobs while dancing with supermodel Cara Delevigne in the raunchy clip.

The video was posted by Kylie Jenner on Instagram during the early hours of Sunday, Jul. 19. It was shot at the afterparty of Cara Delevigne's movie, "Paper Towns," which had its LA premiere screening earlier that night.

"These didn't make it to Snapchat so here you are Instagram," Kylie Jenner captioned the Instagram clip.

Wearing a tan bra and jacket, the 17-year-old "Keeping Up with the Kardashians" star held her breasts in the clip, poked out her tongue, and danced with openly bi-sexual Cara Delevigne.

The wild clip was uploaded by Kylie Jenner on Instagram just a few days after she made a statement about growing up too fast. According to a report from E!Online, the youngest Kardashian-Jenner sibling posted a screenshot of an old episode of their reality show. The image showed Kylie Jenner while she was only around nine or ten years old.

"I promise I won't grow up too fast," Kylie Jenner said the subtitled screencap.

Kylie Jenner joked at the ironic image as if to poke fun at how she was unable to stick to her promise. "Dammit, Kylie!" she captioned the photo.

Us Magazine recently reported how Kylie Jenner slammed haters from Instagram and other social media sites.

"But I've been bullied since I've been 9.... From the whole world, it feels like sometimes... and I think that I've done a really great job in handling all this," she said in a Snapchat clip.

"There are bullies everywhere. So, this was just a little like Snapchat, to tell whoever with their own bullies, that the only opinion that ever really matters is yours and to never change."

"This isn't a pity party though, don't get it twisted... This is for those with bullies out there to know that you're not alone," she added.
